Apologies for taking so long to reply.I was overseas and then got caught up with life and have just found this message in my inbox. I did a history essay on the Davoren boys at uni so I can provide you with a full idea of them.
There were four boys in the family.Michael, my ancestor, was the oldest, then there was Thomas and Peter in the middle and Oliver was the youngest, also the first to emigrate.
Michael was born 1822.Married wife Annie in 1854, she was 19 born 1835, he was 32, both from Clare. They arrived in Adelaide possibly with mother in law Mary Assumption Connell (or she came later) on 19.7.1855 on the Octavia from England. Michael died 9.3.1907 aged 85.After his arrival in Australia he received some govt money to help him get by for 4 weeks, and he became a railway employee in Bowden.He had 10 kids with his wife. Wife died 31.12.1898 aged 63.Given that my grandmother and great grandmother both lived around the Bowden area, I don't think the family spread out too far from there.I can give you all the names of the descendents and birthdays if you want.
Thomas was born 1823, Peter was born 1835, Oliver born 1831. Oliver came to Adelaide first alone, on the Marion, in 1851. Peter came after Michael, in 1857 on the ship Monsoon, married Ann Fitzgerald soon after arrival.She was two years older.Married on the 14.11.1857.Residence was Bowden (possibly with Michael), then Kapunda.Children unknown.(What I know of Thomas is:)Thomas, married Mary Kain, she was born in 1830.Arrived 1858.Married 10.8.1858 in Willunga.(He came on the Stamboul, left 1857 from Southampton arrived Feb 1858).Unknown if wife came from Ireland, but likely.They had two children, John born 1859, lived until he was 78, died 1937.Bridget born 1862, lived for two years, died 1864 with mother in same year, not necessarily at same time.Thomas remarried a Bridget Kearse, born in 1840, 17 years his junior, unknown nationality, father named John.Married on the 11.2.1866 in Marion.Had a daughter Lucy in 1867, who died 1939.Peter and Ann died in Kapunda, 17.5.1885 Peter, 5.6.1896 Ann (or possibly vice versa - my bad noting). Thomas died 17.5.1885. Bridget died 6.8.1901, aged 61.
It's not known who the boys' mother is. We know they come from Clare. We know they were labourers, and at the time of emigration (1850s) the Potato Famine and the Industrial Revolution had made survival hard and money tight in Ireland. More people were moving to the cities for factory work and agricultural crops took up the land, so families had little land to pass on to their children.It was typical in the day to send the youngest out to the colonies to earn some money and either return or send for other family members, and work hard in the new world to build a better life. South Australia was looking for labourers and investment from wealthy property owners in Ireland, they provided incentives for owners to send labourers out to tend the land (such as free ship passage), and the labourers could eventually acquire their own land as well, thus developing South Australia.There was a nomination system, where new labourers could nominate a family member to come join them in Adelaide. I believe Oliver would have nominated Michael, but not so sure about the other two.This farm development angle would be why some of the boys went out to farmland in Willunga and Kapunda.
Anyway, that's about all I know.Hope it's a big help, and puts things into a better context for you.
